Answer:

C. green is not a function, red is a function

Step-by-step explanation:

A curve does not describe a functional relationship if a vertical line crosses it in more than one place. Clearly the y-axis crosses the green curve in 2 places, so it is NOT a function.

There is a very steep section at x=10 on the red curve. It we assume it is simply "very steep" and not "vertical", then the red curve IS a function. If you assume that short section is vertical, then the red curve is not a function, either. My choice is to go with "very steep," not "vertical."

My conclusion is that green is not a function; red is a function.

Point Q is located at (-4, 6). Point R is located at (8, 6).

Bess [88]

Step-by-step explanation:

Hi there!

Given;

Point Q is located at (-4, 6). Point R is located at (8, 6).

Note: Use distance formula.

Now;

$(d) = \sqrt{( {x2 - x1)}^{2} + ( {y2 - y1)}^{2} }$

Keep all values;

$(d) = \sqrt{ {(8 + 4)}^{2} + ( {6 - 6)}^{2} }$

Simplify;

$(d) = \sqrt{( {12)}^{2} }$

Therefore, the distance is 12 units.

Hope it helps!

What is the distance?(-4,2) (-2,-2)

slava [35]

It is 2x and 4y, so you need to use pythagorean theorem. 2 squared is 4, and 4 squared is 16. Add them, and you get 20. The problem is that that won't square to a whole number, so the closest I can get it is the square root of 20, or 2 root 4.
